Refreshing the groups of a running process

Refreshing the groups of a running process

One of the oldest thing that annoy me is the lack of possibility to refresh groups of a running process, specially for X.

me@debian:~$ sudo adduser me plugdev
Adding user `dad' to group `plugdev' ...
Adding user dad to group plugdev
Done.
me@debian:~$ grep '^Groups' /proc/$$/status # On not list group id of plugdev.

Regards.

Refreshing the groups of a running process

At least groups are no longer necessary for most things on the desktop; udev/policykit take care of adding/removing ACLs on device nodes as users log in/log out/active/deactive their terminals.

Being able to revoke access to a file after the user has opened it, however, would still be useful...
